Abstract:
Concentrates for lubricating oil compositions are prepared by mixing at elevated temperature: (i) at least one high molecular weight ashless dispersant; (ii) at least one oil-soluble overbased metal detergent; and (iii) at least one other concentrate additive provided that the additive is first mixed with the detergent or the dispersant.
Abstract:
The invention relates to a synergistic mixture comprising between 1 and 99.9 wt. % of compounds having structural elements (I) in which the free valencies on the oxygen atom and on the nitrogen atom can be combined to form a five-membered, six-membered, or seven-membered ring and the benzene nucleus can still carry substituents on at least one of the free positions, and between 0.1 and 99 wt. % of sulphurous organic compounds having an anti-oxidant action. The synergistic mixture is suitable as a stabiliser for stabilising inanimate organic material, especially mineral oil products and fuels, against the effects of light, oxygen, and heat.
Abstract:
Methods, a lubricant composition, and a fuel composition for lubricating a two-stroke internal combustion engine include a lubricant composition that contains (A) an oil of lubricating viscosity, (B) an additive composition, and (C) a normally liquid solvent having a kinematic viscosity of less than 5 cSt at 100° C. The lubricant composition improves the cleanliness of a power valve of a two-stroke engine.
